nnrrn 1 TATi i BACK-BAND BUCKLE.

To all whom it may concern:

Be it known that I, JAMES A. Hanson, citizen of the United States,residing at Aubrey, in the county of Denton and State of Texas, haveinvented certain new and useful Improvements in Back-l3and Buckles, ofwhich the following is a specification.

This invention has relation to backhand buckles and new and usefulimprovements therein.

The object of the invention is to provide a buckle which will hold inposition either on web or leather backhand and so arranged that anincreased. pull will act to tighten the engagement of the buckle withthe backhand instead of loosening the same and in carrying out thisfeature will also provide teeth engaging on both sides of the backhandin staggered relation.

Finally the object of the invention is to provide means of the characterdescribed that will. be strong, durable, efiicient, and easy ofoperation, simple and comparatively inexpensive to construct, and alsoin which the several parts will not be likely to get out of workingorder.

l/Vith the above and other objects in View, the invention has relationto certain novel features of construction and operation, an example ofwhich is described in this specification and illustrated in theaccompanying drawings, wherein:

Figure 1. is an elevation of the buckle, Fig. 2. is a vertical sectionon the line m00 of Fig. 1. showing a portion of the backhand in thebuckle, and Fig. 3. is a side elevation of a portion of the buckle andbackhand.

In the drawings the numeral 1 designates the buckle and 2, the backhand.The buckle is formed of any preferred metal and suitably finished.

In constructing the buckle a broad base plate is provided. The baseplate at its lower end is contracted to form a central depending loop orhook This book is produced by bending up the metal and directing it overthe contracted portion as shown in Fig. 2. The end of the hook is bentslightly inward to form a spring looking tongue for the purposehereinafter described.

At the upper end and on opposite sides of the base plate, ears 6 areprovided and proj ect at substantially right angles to the plate. Theseears are arranged to receive the trunnions 7 of a flat clamp 8,permitting Specification of Letters Patent.

the clamp to be swung open to receive the backhand and close to hold itin the buckle. The clamp is also contracted at its lower end to producea depending central portion which terminates in a stop 9 directedinwardly from the clamp and adapted to impinge the base plate at a pointadjacent the spring tongue 5. The lower face of the stop is roughened orprovided with teeth as indicated at 10 and with which the end of thetongue 5 engages to lock the clamp in position. It is obvious that bypressing inward on the tongue, the clamp is released and may be swungoutward.

Transversely of the base plate a curved opening 11 is provided and is ofsuflicient width to freely receive the backhand 2. Along the upper edgeof the opening teeth or projections 12 are provided. These teeth arebent slightly so as to project toward the clamp. In the clamp similarteeth 13 are provided and bent slightly inward toward the base plate.However the teeth 13 are so disposed as to project in staggered relationto the teeth 12 and with their points substantially over theintersections of the teeth 12. This disposition and arrangement of theteeth is very important and is one of the best features of my inventionfor the reason that when the backhand is passed through the buckle asshown in Fig. 2 the teeth will bite into it on both sides and the teethon one member will have a tendency to force the backhand into the spacesbetween the teeth of the other member and thus firmly hold the buckleagainst sliding or displacement on the backhand irrespective of the factthat the backhand is made of leather or webbing. It is also obvious thateither an upward pull on the backhand or a downward pull on the bucklewill cause the teeth to more firmly engage the backhand.

What I claim is:

The combination in a backhand buckle, of a base plate flat throughoutits length, ears turned up from the plate at each side of one end, theopposite end of the base plate being cut away at each side, a hookformed from the cut away end of the plate and bent thereon, a springlocking tongue extending inward at an angle from the hook, the baseplate having a transverse opening with one curved side and one straightside, teeth projecting from the plate into the opening on the straightside, the teeth having their points bent upward, a flat clamp plate hav-5 ened face engaged by the spring locking ing trunnions at one endengaging in the tongue.
